Abstract (en)
An improved transmitter having protection from undesired out-of-band radiation caused by high frequency components in a supplied signal to be transmitted uses means for determining when the supplied signal is such as to cause out-of-band radiation. A resulting control signal then reduces the amplitude of the higher frequency components of the supplied signal relative to the remainder of the signal, thereby preventing out-of-band radiation.
